Red Bull still considering engine switch

Even at the apparent conclusion of the FIA-FOTA war, it seems Red Bull is still on the market for a new Formula One engine supplier for 2010.

Earlier this year, the fact that Christian Horner openly mused not signing another customer contract with Renault was believed to be based on speculation that some carmakers may not be on next year's grid.

"Who knows what engine manufacturers are still going to be there in 2010?" the Red Bull boss said in April.

As the FOTA war ended late in June, however, part of the peace agreement was the manufacturers' commitment to F1 at least until the end of 2012.

"So in the past, if somebody was worried, maybe after Honda left or somebody else, not now," Luca di Montezemolo said.

But it seems Red Bull Racing, whose Renault contract runs out this year, is still considering switching to Mercedes power.

Horner told the latest edition of Germany's Auto Bild: "The Mercedes engine is good, but there is no time pressure.

"Brawn demonstrated that it is possible to change engine even at a late stage," the Briton added.
